CARBONATING APPARATUS.

Specification of Letters Patent.

Patented Dec. 8, 198.

Application led December 9, 1904. Serial No. 236,191.

To all whom it may concern:

Beit known that I, HENRY PEIN, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented a new and useful Improvement in Carbonating Apparatus, of which the following is a specification.

The object of my invention is to provide an apparatus of this class which is suitable for use in automatic vending devices, and which will at all times, carbonate beveragesin a suitable and proper manner, while the said apparatus is in use in the vending machine.

or a more particular description of my invention, reference is to be had to the annexed drawing forming a part hereof, in which- Figure 1 is a longitudinal sectional view of the complete apparatus taken on line 1-1 of Fig. 2, looking in the direction of the arrows. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2, looking in the direction of the arrows. Figs. 4 and 5 are a side elevation and plan respectively of one of the weight controlled levers. Fig. 6 is a sectional view taken on the line 6-6 of Fig. 3, looking in the direction of the arrows. Figs. 7, 8, and 9 are a plan, side, and end elevation respectively, of the guard mechanism. Figs. 10 and 11 are a side elevation and plan respectively, of a lever for controlling the air vent. Fig. 12 is a sectional view showing the lower end of the Vair vent.

Throughout the various views of the drawing, similar reference characters designate similar parts.

The carbonator 1 comprises a casing 2 which may be given any suitable or desired shape, although it is preferably made as shown, and is given any suitable lining, such as the porcelain or sheet tinlining 3; this latter lining is preferred, because it is not attacked by the chemicals used, not liable to breakage, although it is obvious that any lining may be used, as is well understood. The zlower end of the carbonator 1 is closed by a disk 4 which is supported by feet 5 which are shown diagrammatically in Fig. 1, and these feet, the disk, and the case 2, are clamped together by bolts 6, which fix the parts together. Packing or gaskets 7 and 8 make the joints tight and prevent all leakage. At the upper extremity of the case 2 is provided the water inlet and gas outlet 9 which comprises a T having a central perforation 10, in which is screwed or otherwise suitably secured, a valve 11, the plunger 12 of which is normally kept to its seat by means of a coiled spring 13 and the joint between the piston 12 and the valve seat is made tight by means of packing 14. A pipe 15 suitably connected with the valve 11 by means of the union 16 connects the carbonator with the source of the water supply. As this water is to be used for drinking purposes, it is preferable to filter it before it is supplied to the carbonator, but this is a matter which is left to the discretion of the operator. The T 9 is also provided with two other ports, one of which may be either closed by a plug or connected with a pressure indicator or any other device such as an auxiliary cylinder, as may be desired and the other is connected to a mixer, as described below. The casing 2 is also preferably, but not necessarily, provided with two valves 17 and 18 connected by a glass tube 19. These three parts form a water gage to enable the operator to determine at any time, the amount of liquid in the carbonator. While only one form of water gage is shown, it is obvious that any other form may be substituted, if such a substitution is deemed advisable.

Near one side of the carbonator 1 is the air vent tube 2O which passes through the disk. Leakage around the tube 20 is prevented by a nut or shoulder 21 near the lower end of the tube which rests on a gasket or acking 22, the gasket being pressed against tlie disk 4 by the nut 23 which is screw-threaded to the outer and lower end of the tube 20. This nut 23 has two downwardly extending arms 24 and 25 which are unitedby a pivot pin 26, on which is fulcrumed a lever 27. The lever 27 has at or near one end a weight 2S which slides on said lever and is held in any desired place by a set screw 29. The other end of this lever 27 is provided with a packing 30 which is adapted to bear against the lower end of the tube 20 and to be held with an air-tight joint against the lower end of this tube. The weight 28 is so placed that the gasket 30 will be removed from the tube 20 when the ressure in the carbonator exceeds a certain imit, as will more fully appear below.

The upper end of the tube 20 is provided with a guard 31, which guard comprises a casting 32 with two radiating arms 33 and 34 which are united by and integral with, a curved portion 35. The curved portion 35 is preferably so shaped as to exactly conform with the interior of the casing 2. Another rod 36, altogether separate from the guide rods 33, 35, and 34, extends in the opposite direction from the casting 32, and this rod 36 is provided with a downwardly curved end 37 which is adapted to rest against one wallI of the casing 2. The casting 32 is split at 38, and rovided with two projections 39 and 40 whic are screw-threaded and united by a screw 41. The split 38 extends to a central bore 42 which is adapted to t the tube 20 and to be clamped thereon by the screw 41, and extending upwardly from the casting 32 is a bifurcated projection 43 through which passes a pin 44. A lever 45 is pivoted on the pin 44, and has one end extending over the tube 20, and the other end extends towards the other side of the casing 2, as will appear below.

The lever 45 is preferably made in two parts, one of which is a casting 46 and the other a bent wire 47. The casting 46 has a weighted end 48 which is connected by a slotted neck 49 with the part 50, which receives the pin 44. The end 47 is provided with a loop 51. The up er end of the tube 20 may be closed by a p ug 52 which is provided with a lower portion 53, which is angular in cross section, and a collar 54 which is adapted to rest on the end of the tube 20, and is made true so as to form a gas-tight joint therewith. This lug 52 is also provided with a stem which extends through the slot in the neck 49, and is held in place by means of a cotter in 55. The stem 52 is slightly reduced w ere it goes through the neck 49, so that the valve formed by the end of the tube 20 and the shoulder 54 is opened or closed by the action of the lever 45.

Arod 56 extends through the loop 51, and is supported by this loop and secured in place by means of a pin 57 or any other suitable means. An ordinary ball float 58, made in the conventional manner, slides upon the rod 56, and causes this rod to be raised when the float 58, strikes the loop 51 of the lever 45, as will appear below. The lower end of the rod 56 passes through a collar 59 and is Eivotally connected vsdth a weighted lever 60 y means of a pivot 61. The collar 59 forms the lower limit of the movement of the iioat 58 and this iioat rests thereon when the carbonator is out of use or nearly ein ty.

The lever 60 is fulcrumed in a Lbracket 61 which is secured to the disk 4. The bracket 61 contains two upwardly extending arms 62 between which the lever 60 is pivoted on a pin 63, and the stop 64 limits the movement of the lever 60 in both directions, as will appear below.

This lever 60, which is preferably casting, although it may be formed in any suitable manner, is provided with a weight 65 at the end farthest removed from the pivot 61, and near its fulcrum 63 which is provided with two curved stops 66 and 67, which extend upwardly and in opposite directions, so as to face each other. Below the fulcrum 63 is a downwardly extending projection 68 which is adapted to impinge against the stop 64 when the pivot 61 is raised to the upper limit of its movement.

When the pivot 61 is in the lower limit of its movement, the stop 64 im inges against a small projection 69, as is c ear in Fig. 1. The lever 60 is also provided with a small projection 70, which impinges against another lever in the manner described below. A second lever 71 with a weight 72 is bifurcated at its lower end to straddle the lever 60, and is fulcrumed on the same pivot 63. The movement of the lever 71 is limited by the projections 66 and 67 on the lever 60, and impinges against one or the other of these with a ham1ner-like action, when the lever 60 is shifted.

The projection 7 0 on the lever 60 impinges against the extreme end of a lever 73 which is fulcrumed to a bracket 74 by a pin 75. The bracket 74 is secured to the disk 4 by a nut and threaded end 76, as is apparent in Fig. 3. The lever 73 is of the second order, and has a bearing at 77 on a spindle 78 which extends through the casing 7 9. The casing 79 passes through an opening 8O in the disk 4 and gaskets 81 rest on top of this disk and surround the mouth of the opening, and which press against the disk 4 by means of a `nut 82, whereby a tight joint is formed between the casing 79 and its shoulder 83 and the disk 4. A coiled spring 84 impinges against a nut 85 on the valve stem 78 and causes the valve 86 to fit snug and tight against the casing 79. This joint is further assisted by the gas pressure which is larger than the pressure inside the carbonator, so that the valve must be opened against the pressure of the gas, when gas is admitted to the carbonating apparatus.

Liquid is drawn from the carbonator through any suitable means as a pipe 87, and when so drained is drawn to any desired point. j

While the above described carbonator may be used for a variety of purposes, and under a great number of conditions, it is preferable to employ it in automatic vending machines, as is designed for this use.

From the foregoing, the operation of my improved apparatus will be readily understood. Assuming the parts to be in the position indicated in Fig. 1, except that the free openings in the T 9 are suitably closed or connected, water is admitted through the pipe 15 and valve 11, and falls on the disk 4 in the casing 2; air escapes through the tube 20 and by the rubber packing 30 held by the weight 28. This continues until the float 58 is forced upward into engagement with the loop 51, when the collar 54 is forced downward until it rests firmly and with the airtight joint on the tube 20. Meanwhile the iioat 58 forces the rod 56 upwards and through the pivot 61', the lever 60 thereby lowering the ball 65 at its other end and throwing over the weighted lever 71, which is forced to a vertical position by the projection 67, and then falls of its own weight against the projection 66, thereby producing the eifect of a light hammer blow. The rod 56 moves upwardly until the projection 68 impinges against the stop 64, when its further upward movement is limited, and at the same time, the end of the lever 78 is forced downwardly, thereby opening the valve 86 by depressing the valve stem 78, whereby gas is admitted into the cylinder. It will be noticed that the gas is admitted only when the air vent is closed and continues to be admitted until the carbonated water is withdrawn through the pipe 87 to such an extent that the float valve rests with all its weight on the collar 59. When this happens, the weight of the float, 58 over-balances the weights 65 and 72, and restores them with a slight hammer-like action from the lever 71, when the lever 73 is raised sufficiently to permit the spring 84 and gas pressure to close the valve at 86. The water pressure is then suflicient tov enable water to enter as above described, Water is admitted automatically when the gas is shut oif and at the same time air is allowed to escape. When enough water is in the carbonator, the air vent is closed, water shut 0H and gas is then admitted, and all this is done automatically.

The function of the guard 31 is to hold the tube 20 true, because the parts 36 and 35 engage the inner wall of the casing.

From the foregoing, it is evident that my invention may be varied in many details or particulars` withoutv departing from its scope, nor reducing its efficiency, so that it should not be considered as being limited to the precise structure herein shown and described, but should be regarded as broad enough to cover all structures which come within the scope of the annexed claims.

Having thus described my invention, what I claim is z- 1. In a carbonator or similar device, an air vent comprising a tube with a valve at its top controlled by a float, and a weight controlled valve at its lower extremity, means for admitting water, and means for admitting gas.
